CVE-2026-28376: Vulnerability in Grafana Grafana OSS
The Grafana Live push endpoint can be exploited to cause unbounded memory allocation by sending a large or streaming request body, potentially leading to out-of-memory conditions. An authenticated user with access to the Grafana Live API can trigger this issue.
AI Analysis
Technical Summary
The Grafana Live push endpoint in Grafana OSS versions including 8.0.0, 11.6.14, 12.0.0, 12.2.8, 12.3.0, 12.3.6, 12.4.0, 12.4.3, 13.0.0, and 13.0.1 is vulnerable to unbounded memory allocation when an authenticated user sends a large or streaming request body. This can cause the application to consume excessive memory, potentially leading to out-of-memory conditions and denial of service. The vulnerability is tracked as CWE-770 (Allocation of Resources Without Limits or Throttling). The CVSS v3.1 base score is 6.5, indicating a medium severity. No patch or official remediation guidance is currently available, and no known exploits are reported in the wild.
Potential Impact
An authenticated user with access to the Grafana Live API can exploit this vulnerability to cause the Grafana server to allocate excessive memory, potentially leading to out-of-memory conditions and denial of service. There is no impact on confidentiality or integrity reported. The primary impact is availability degradation due to resource exhaustion.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the Grafana Live API to trusted users only and monitor resource usage to detect potential abuse. No official patch or temporary fix has been published by the vendor at this time.
